Lenovo is blaming it’s IBV, so, it’s 100% that there’s others OEM’s that have this vuln in their products

Did some more research, this is definitely more widespread that I thought, there's another driver with the same vulnerable function

Any other Gigabyte motherboards vulnerable? I have one of their H97 boards

presumably, no reason for Gigabyte X99 boards to not be vulnerable? Any mitigation possible without new fware?
